Faces become distorted, strange and look glitchy when looking through camera view
It looks like Z-fighting, probably the clip distances is set to a very large number.

The clip range should encompass your scene, not the whole universe. A large clip range will result in lower depth precision, creating Z-fighting, where the render engine cannot determine which surface is in front or which one is behind. In other words blender cannot tell apart faces that are parallel but in close proximity with each other.
